GLUE-APPLYING MACHINE. l

To all whom it may concern:

Beit known that we, JAMES A. BUTLER, of Winthrop, and CLARK REYNOLDS and AL- BERT J. SEAMAN, of Boston, all in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in GlueApplying Machines; and we hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in machines for applying liquid glue to paper and particularly to sheets of paper to be thereafter used in covering box bodies.

One object of the invention is to deliver the liquid glue in a thin even layer to the paper. y

Another object of the invention is to guide the sheets of paper to the delivery roll.

Another object of the invention is to so construct a machine of this nature, that, the sheets of paper will be positively stripped from the glue delivery roll turned upward from the stripper.

Other objects of the invention will appear from the following description.

The invention consists in such peculiar' features of construction and combination of parts, as shall hereafter be more fully described and pointed out in the claims.

Figure 1, represents a side elevation of the improved glue applying machine. Fig. 2, represents a similar view with the side frame removed, the cross members and shafts being shown in sections as on a line 2-2 Fig. 4. Fig. 3, represents an enlarged view of one of A Fig. 4, represents a partial plan view of the improved machine.

Similar numbers of reference designate corresponding parts throughout.

As shown in the drawings 5 and 6 represent the side frames on which the mechanism is supported, these frames 5 and 6 are suitably braced, and are connected by bolts, and

are supplied with arms 7 and 8, and the up' per member 9 with its inclined members 10 and 11, as shown in Fig. 1. ln bearings of the frames, 5 and 6 between the arms 7 and 8 is journaled the shaft 12, carrying the glue applying roll 13, between said frames, and the large gear 14 outside the frame 6. At the rear portions of said frames 5 and 6 is rotatably mounted the shaft 15, on which the lever arms 16 and 17 are fixed, the mem- Patented March 24, 1908.

Serial No. 344,004.

ber 16 has the pin 18, while the members 17 have the bearings 19 in which the'studs 20 of the concave glue reservoir 21 are journaled, whereby said reservoir may be swung towards and from the glue applying roll 13, provision is made for supporting said reservoir in the desired position by means of the notched arm 22, pivoted on the rod 23 extending between the side frames 5 and 6, the notches on said arm being designed to engage with the pin 18 of the member 16. At the forward, or feeding in, end of the frames 5 and 6 is journaled the shaft 24 having the scraper blade 25 and the arms 26--26 by means of which the shaft 24`Inay be rotated to adjust the scraper blade 25 towards or from the glue applying roll, the arms 26-26 being secured in the adjusted position by means of the clamp screws 27-27. At the forward end of the machine the feed table 28 is pivoted to swing between the frames 5 and 6, and is supported by the rods 29-29, this table has, at its inner edge, the curved metal lip 30 the edge of which extends close to the periphery of the roll 13 and, above the edge of this lip 30 is the guide roll 31 rotatably mounted in the bracket arms 32-32 which are pivotally mounted on the table 28 and have adjusting screws 33-33.

Journaled in bearings of the frames 5 and 6 is the shaft 34 having the handle 35 and the cam 36, which is adapted to work against the cam 37 of the frame 5, when said shaft is rotated to effect the longitudinal movement ofthe shaft to draw the drive pulley 38, rotatable on said shaft 34, towards the frame 6 to engage the clutch member 39 of said pulley into engagement with the clutch member 40 of the gear 41 loose on said shaft 34 and meshing with the gear 14 to drive said latter gear; when the clutch members 39 and 40 are in the positions shown in Fig. 4 of the drawings the coiled spring 42 located therebetween tends to keep them apart. 1

Between the frames 5 and 6 abovethe glue applying roll 13 are rotatably mounted the belt guide roll 43 having the pinion 44, the belt drive roll 45 carrying the belt 45 and having the pinion 46, meshing with the pinion 44, and the brush roll 47 furnished with 'spirally arranged bristles. Adjacent to the bearings for the roll 43 other bearings are formed in the frames 5 and 6 to receive the rod 48, of said bearings, that on the frame 5 has the cam 49, and the rod 48 has,

loosely mounted thereon, the handle 50 with the cam 51 adapted to work against the face of the cam 49 to effect the longitudinal movement of said rod 48 when the cam 51 is rotated to draw the clutch member 52 of said rod 48 into engagement with'the complemental clutch member 52 of the gear 54 which, through the engagement of this latter gear with 'the gear 14 effects the rotation of the rod 48 and the pinion 55 thereon and through the engagement of said pinion 55 with the pinion 44 drives the pinions 44 and 46 and their shafts,

On the shaft of the brush roll 47 outside the frame 5, is the pinion 56 which is driven from the gear 57 mounted on the end portion of the shaft 45. Pivoted on a pin eX- tending from the gear 56 is the reciprocating cam 58 which has the slot 58. The stripper vibrator rod 59 is slidably mounted in the bearings of the frames 5 and 6 and extends through the slot 58/ of the cam 58 and at, this end, is furnished with the cam 60 against which the cam 58 works when reciprocated by the rotation of the gear 56, to effect the movement of the rod 59 in one direction, against the action of the spring 61`mounted on said rod 59 and bearing against a collar thereon, and against a fixed part of the machine. ()n the rod l59 is mounted a series of collars 63-63, between which are frictionally engaged the stripper arms 64-64 having cut out portions to receive the rod 59 and tapering 'fingers 6565 adapted to bear against the periphery of the glue applying roll 13 as the rear ends of said arms 64 are yieldingly sustained by the springs 66-66 secured to said arms and to the cross plate 67 which is carried by the brackets 68-68 on the side frames 5 and 6.

Mounted on the rear portions ofthe side frames 5 and 6 are standards, as 69-69 Fig. 1, on which is supported the table 70, and at the ends of this table is liournaled, in bearings of the frame members 9 9 the roll 71 carrying the glue receiving belt 72 which also passes over the roll 73 liournaled in bearings in the Itake up arms 74, pivotally mounted on the frames 5 and 6 and having adjusting screws as 75, by means of which the arms 74 may be swung away from the roll 71 to tighten the belt 72, and to draw the same out of contact with the glue applying roll 13, when desired, the purpose of the belt 72 is to receive glue from the roll 13 and deliver said glue to transfer dies pressed against the upper reach of the belt 72, when it is desired to :apply glue in particular patterns to box Wrappers, such as are known as loose wrappers. As said transfer dies form no part of the present invention, they are not shown in the drawings.

In starting the machine, the glue applying roll 13 is, preferably, 'lirst operated for a time to determine the distribution and condition of the glue ;l power is of course applied to the pulley 38 in any well known manner and said pulleyis moved to bring its clutch member 39 into engagement with the clutch member 40, of the gear 41 by swinging the handle 35 in the direction to rotate the cam member 36 against the cam member 37; the gear 41 is thus driven from the pulley 38 and in turn drives the gear 14 of the glue applying roll 13, and this roll takes glue from the reservoir, and carries a film of said glue upward, the thickness of this film being determined by the adjustment of the scraper 25. After suitable manipulation of the roll 13, the handle 50 is swung to rotate its cam member 51 againstvthe cam 49 to draw the rod 48 lengthwise, whereby the clutch member 52 of said rod is brought into engagement with the clutch member 53 of the pinion 54 and,'as

this pinion is driven from the gear 14, the 5 rod 48 and its pinion 55 is driven and motion is imparted through the pinions 44 and 46 to their respective shafts and from the gear 57 to the pinion 56; the reciprocation of the cam 57 is effected to cause the vibration of the rod 59 and the stripper arms 64-64 engaged between the collars 63-63.

The sheets of paper to receive glue are placed on the table 28 and are fed forward by the hand over the upwardly curved plate 30, whereby the forward edges of the sheets are curved upward, until said edges touch the glued periphery of the roll 13 where they adhere to the glue on said roll, and are carried up ward, being carried under the guide rod 31 which smooths the paper and prevents wrinkling of the same while it guides the paper towards the roll 13. As the forward edge of a sheet of paper approaches the stripping position, the constant vibration of the stripper arms, 64, tends largely to effect the engagement of their tapering ends beneath the edge of the paper, this action being assisted bythe springs 66-66 which eXert tensions on said arms 64-64 to bring the ends 65-65 constantly into contact with the periphery of the roll 13, the combined ends 65-65 of these arms also form an incline over which the glued paper is directed upward between the belt 45 and the brush roll 47, wher'e it is acted on by the brush on said roll to direct it on to said belt, the spiral arrangement of the bristles on the brush roll also acting to smooth out any wrinkles in the paper.

Having thus described our invention, we claim as new and desire to secure by Letters Patent.
